Need help updating Wiiflow v1.1 R25

A friend of mind who is not a noob like me softmodded my wii a few years ago and it's been great, no problems. I recently got SkyLanders Giants for my son and am unable to use the power portal. I load games from a hard drive that is connected to one of the usb ports on the back of the wii. The power portal doesn't work in the other usb port.

I figured I'd post a sys check and get some advice from there. I read that guide but I don't have the homebrew channel, so I stopped there. I read the softmod any wii guide, figuring that would tell me how to install the homebrew channel. It does, but I don't think I want to overwrite my current softmod. I've never had any problems with it, I just want to be able to use the power portal with the Skylanders game.

I didn't make an intro post, but did come across one from another member and took a look at the links that were provided. I'll keep reading, I know the answer is there. I'll also look for the Homebrew channel. I only scrolled over 1 screen and didn't see it, but maybe it's further over. I tried playing from the game disc but was prompted to do a system update. I don't remember much that by friend told me about softmodding, but i do remember he said never to do a system update.

I scrolled all the way across and didn't see HBC. My friend sent me a link to pimp my wii and said that would update everything. he's the same guy that did the softmod the first time and i trust him but i'm too much of a noob to feel comfortable using that. I'm re-reading the softmod any wii guide now.

Read the first line of THIS, then go back to the softmod any wii guide.

I finished reading the softmod any wii and fat32 guides a couple times, so I'm pretty comfortable but have one more question. If I follow the softmod any wii guide, will I have to do anything else to continue playing my backup copies from my hdd? I don't have to reformat and/or partition my hdd do I?
